A new high-resolution gamma ray spectrometer operating in the energy range of 0.05 to 10 MeV was sucessfully balloon-flight tested. This system uses four crystals in a single cryostat as prime sensors. A 6.35 cm thick CsI(Na) shield provides background rejection and collimation, defining a solid angle of 0.095 sr. Cooling is provided by a liquid-nitrogen dewar. The system was highly stable with spectral resolution of better than 2.5 keV at 1 MeV for the flight duration.
